Kiwi PDF offers several display modes to suit different reading conditions and document types.
Scroll direction
- Open the PDF and tap the Display options button (three sliders) in the middle of the bottom bar.
- Scroll Direction — Vertical scrolls the pages up and down; Horizontal turns them sideways like a book.
- Background — white, sepia or dark page tone for comfortable reading.
- Fit — Fit Width fills the screen edge to edge; Fit Page shows the whole page.

Background colour
Pick one of the three circles under Background in Display Options: white, sepia (warm, easier on the eyes for long reading) or dark (for low light).
The background tone only changes how the page looks on your screen — the PDF file itself is not changed.
Zoom
Pinch to zoom in or out anywhere on the page. Double-tap to fit the page width, then double-tap again to return to the previous zoom level.
Fit to width vs. fit to page
- Fit width — the page fills the screen edge-to-edge horizontally. This is the default and gives the most readable text size.
- Fit page — the entire page is visible at once, useful for checking layout.
